Problems solved by technology

However, the support ring 240 on the outer ring of the step ring 230 can prevent the deformation of the outside, and the inner deformation of the step ring 230 will cause loosening and imbalance of the joint state between the parts, resulting in uneven rotation and shortening the life of the parts.

Embodiment Construction

[0019] The specific implementation examples are given below in conjunction with the accompanying drawings to illustrate the rotor of the induction motor of the present invention.

[0020] Such as image 3 As shown, the induction motor is firstly composed of a stator 100 wound with coils, and a cylindrical rotor 300 in which an induced current is generated by a rotating magnetic field generated by alternating current inserted into the stator 100 and coils 110 wound around the stator.

[0021] The stator 100 includes a superimposed body 120 formed by stacking steel plates having a predetermined shape, and a winding coil 110 wound on insulating paper formed on the superimposed body 120 .

[0022] Such as Figure 4 As shown, the rotor 300 is composed of a cylindrical body 310 with a predetermined length, a plurality of fixed rods 220 formed by inserting through the cylindrical body 310 to form a plurality of concentric circular shapes, respectively located at both ends of the cyl...

Abstract

A rotor for induction motor is composed of a cylindrical body, multiple fixing rods passing through the holes in the cylindrical body, segmental rings at both ends of said cylindrical body and bound with said fixing rods, and the supporting rods for reinforcing the segmental rings. Said cylindrical body is made up of the circular silicon steel sheets. Its advantages are no deformation, and high rotation stability and reliability.

Description

technical field [0001] The invention relates to an induction motor, in particular to a rotor of the induction motor which can minimize deformation of components caused by centrifugal force generated during high-speed rotation. Background technique [0002] In general, an electric motor is a device that converts electrical energy into kinetic energy, and there are many types of it. [0003] figure 1 is a diagram of a conventional induction motor. As shown in the figure, the motor is composed of a stator 100 wound with coils, and a cylindrical rotor 200 that induces current by being inserted into a rotating magnetic field generated by an alternating current inside the stator 100 and coils 110 wound around the stator 100 . [0004] The stator 100 includes a stacked body 120 formed by stacking steel plates formed in a predetermined shape, and a wound coil 110 wound on insulating paper formed on the stacked body 120 . [0005] The rotor 200 is as figure 2 As shown, a circula...
